I got it to 60% now at a constant with this small humidifier working on 1 out of 3 power. With one window open and if i turn down the carbon filter.Yes ya need to get that plant under some more humidity.
Seedlings need humidity and that high a vdp can cause problems.
However. We have seen these plants adapt to some pretty marginal conditions and do ok.
I guess i should turn my heat up to atleast 28,29 to get into the light blue zone?Here is a neat tool to see what the recommended humidity for different temps. The closer you stay to the good the better it will be.
But again this plant can adapt to higher or lower humidity but it does not like quick changes where the plant environment goes up and down more than 2.5% in a short time, say 10 minutes for long periods of time.
You just put in your temp and humidity and it tells you where you are.

Will do ill try to keep it around this what i have now till i can get my hands on a bigger humidifier. Hoep they can do well with 62% humid and 25c.Well perhaps.
The vdp listed is not outrageous in fact at one time I had a tent with 2 in flower and 2 in late seedling early veg at that point, about 1.2 vdp.
What I also have is a well controlled environment so my temp moves about .2 degrees uup and down and my humidity stays withing 2% of settings.
This allows the plant to adapt. What stalls plants is the wild swings that halt and restart transperation events that power the plant.
This environmental control raises transperation rates and the pressure inside the plant. This results in a tabletop flatness to the leafs and it is an indication that the lights and the environment are dialed pretty well.

I have already made some environmental decisions based on this. I ran plants. For a few weeks at a lower temp because it had rained and a few other issues had driven the humidity up. This made my humidity swings over 3% up and down and it was multiple times an hour. Totally stopped leveling leafs.
Reduction in temp from 80 to 78 put it back in the zone at same vdp I wanted just not the temp I wanted.
Go with stability over temp and humidity as long as you are in the lane.
No, you don't need the carbon filter at this point in the grow. The filter is just to absorb smells in flower. I usually disconnect the filter in veg and early flower to extend the life of the carbon. You do still need the exhaust fan for air exchange but at this stage you can run it very slow if it helps keep a stable environment. Good LuckI got it to 60% now at a constant with this small humidifier working on 1 out of 3 power. With one window open and if i turn down the carbon filter.
Is thw filter needed much at this phase? If not i could keep this humidity without him. As soon as i turn him on the humidity drops to my room humid.
Thank you, they do recieve the most love me and my wife can offer.They are very pretty, great job!
What nutrition chart has you reducing nitrogen that early.A small update on my babies.
SHerbet queen is 1 week in flower already. Milky way and blue cheese both joined the early flowering club. Do these look fine to you. I feed them once every 2 watering. I use half the recommended dose. I still use veg nutrition in addition to flowering. I plan on stopping in a week and just give them flower nutrs.
Well im not. Blue cheese was planted almost 2 weeks after sherbet. Milky way was 1 week later. So i am aware they are different plants and have different needs.What nutrition chart has you reducing nitrogen that early.
Plant is still growing even the puff ball showing one and the others appear to be just a bit behind.
Do not use gang mentality when watering and giving nutrition. Look at them as different plants and add stuff as they need.
